1.6 Design
1.6.1 Main components
Main components of the machine are the following: 1 – Door; 2 – Latch;
3 – Light box; 4 – Control panel; 5 – Loading tray; 6 – Deflector; 7 – Leg;
8 – Paper/carbon filter assembly; 9 – Grease filter; 10 – Oil tank; 11 –
Basket; 12 – Heating element; 13 – Drain valve:
1.6.2 Control panel
Control panel has the following items: 1 – ON/OFF button; 2 – 4-digit
display; 3 – program buttons:
7

1.6.3 Light box
Light box media can be easily changed. To change the media, first, slide
the door upper edge (that is held by magnet locks), and second, remove
the media:
1.6.4 Air filter
Unit has 3-stage air-filter, so no special exhausting hood is needed. First
stage is a grease filter, second stage is a paper HEPA filter, and third stage
is a carbon filter. Up to 98% of smallest particles less than 0,3 micron are
retained.
1.6.5 Low oil and water detection
The machine can detect low oil and water in oil. If oil is low, then the
machine will cut off the power supplied to the heaters and notify the op-
erator. If considerable amount of water presents in the oil, then machine
will also cuts off the power supplied to the heaters and notify the operator.

2 Intended use
2.1 Normal operation order
Make sure that machine is assembled, and all components are in its place
and oil drain valve is closed. Fill frying tank with oil up to the mark (8
liters), set the basket into dumping mechanism, and latch the door. Put a
suitable container for ready made product in front of the machine, under
the loading tray, it may be GN container, for example. When the machine
is turned off, light box is not lit, and display shows "OFF" message.
Press ON/OFF button to turn the machine on. The basket will be re-
turned to lower position, oil is started to be heated (by default to 180◦C);
ventilation and backlight are on. Heating progress is to be visualized on the
display. In the beginning of heating process, display shows four blinking
letters: HHHH. While temperature is rising up, there are less Hletters
blinking. Once the set point is reached, display shows the temperature
set value (180 for example). The machine is now ready for operation. To
prepare a portion of product, do the following:
1. Open the loading tray and put the product in the tray (not more
than 500 g per batch).
2. Close the tray.
3. Press a program button.
4. Wait until the product is being discharged automatically.
DO NOT open the tray while product is being
cooked!
Each program button corresponds to a timer that defines the product
residence time. Timers are adjustable, so it is possible to tailor the ma-
chine for virtually any product.

2.2 Shutting down
To end the operation, press ON/OFF button, the lightbox and the heater
are turned off. After turning off, ventilation operates for 5 minutes more,
and then automatically is turned off.
2.3 Adding oil
If "OIL" message appears on the display, it means that the machine has
detected low oil level. Do the following:
1. Turn the machine off.
2. Close loading tray
3. Open the door
4. Carefully pour oil into the frying pan up to the MAX mark.
5. Close the door
6. Turn the machine on.
2.4 Changing oil
The same load of oil can be used for certain time, which depends on the
product used, settings, and other factors. It is recommended to use special
tool or testing strips to find out when oil should be changed. To change
the oil, daily cleaning procedures must be performed, see Technical Main-
tenance section.

2.5 Water in oil (Err4)
Err4 message means that water in oil protection system was tripped. This
can happen either if there is water in oil, or if the machine has been turned
on with oil that was already warm, about 100◦C. To fix the error, do the
following:
1. Turn the machine off and turn on again. If the message is still here,
proceed to the next step.
2. Turn the machine off and drain the oil. Make sure there is no water
in the oil. Fill the tank with oil, and turn the machine on.
2.6 Oil temperature adjustment
1. Turn the machine off.
2. Press and hold ON/OFF button until Pr appears on the display,
then release the button.
3. Press ON/OFF button again, Pr-C appears on the display. Press
button #1 to decrease, or button #2 to increase the value. By default
the temperature is 180 ◦C.
4. The machine automatically returns back to standby mode after 10
sec of idle.
2.7 Program timers adjustment
1. If machine is on, turn it off by pressing ON/OFF button.
2. Press and hold ON/OFF button for 3 seconds, Pr appears on the
display.
3. Choose a program (buttons #1 to #4).
4. Set the time, by pressing buttons #1 (decrease) or #2 (increase).
11

5. Press ON/OFF button to save the new value.
6. To set another timer, repeat steps 3 to 5.
7. The machine automatically returns back to standby mode after 10
sec of idle.
3 Cleaning and maintenance
ALWAYS unplug before cleaning!
DO NOT use excessive water for cleaning!
DO NOT use aggressive solutions for cleaning!
DO NOT use sharp tools or items for cleaning!
Wait until oil is cooled down!

2. Attach oil drain hose to the valve, get ready a drainage container,
and put free end of the hose into container.
12

3. Open the valve and wait until oil is drained to the container.
4. Close the valve.
5. Take out the loading tray assembly, and detach tray and deflector
(Fig.1).
6. Take out the basket (Fig.2).
7. Lift up the heaters assembly until it is locked in upper position (see
Fig.3). To unlock the heater, pull it up, and pull up the pin on the
left side of the chamber, and then put the heater down.
8. Take out the frying tank. Pour the oil remains to the drainage con-
tainer (see Fig.4).
9. Take out paper/carbon filter assembly (see Fig.5). DO NOT wash
or soak the filters!
10. Take out the grease filter (see Fig.6).
11. Thoroughly wash basket, tank, heaters assembly, internal surfaces
of the chamber, grease filter, loading tray and deflector. Use warm
water and mild detergent suitable for stainless steel.
12. Wipe dry immediately.
